Hey guys I know why the hdd is buzzing, but I was thinking it only happens to old hdd's.. what about new ones? I've bought blacks from ncix and they haven't buzzed, but this hdd that I got from bewawa buzzes as I type (also a wd black). Is it normal? Is it a sign of eminent failure? Should I return/exchange it? My case is a haf922, using the drive caddies as provided. Previous black from ncix was also used in a caddy. Thanks.
